Abstract

The invention discloses a distributed Internet of things serial server. The distributed Internet of things serial server comprises a terminal device, a collection server and an Ethernet; wherein the collection server comprises a RS485 communication module, a MCU master control module and a TCP/IP network communication module; the terminal device is communicated with the RS485 communication modulein a both-way manner; the RS485 communication module is communicated with the MCU master control module in the both-way manner; the MCU master control module is communicated with the TCP/IP network communication module in the both-way manner; and the TCP/IP network communication module is communicated with the Ethernet in the both-way manner. The distributed Internet of things serial server provided by the invention solves the three problems that the accessed equipment is less, the network transmission efficiency is low, and the server load is heavy in the communication of a traditional serialserver when the Internet of things devices are connected to the Internet in a large scale.

Description

technical field [0001] The invention relates to the technical field of serial port server Internet of Things equipment, in particular to a distributed Internet of Things serial port server. Background technique [0002] In the communication network of the existing serial server IoT devices, it plays the role of data bus (such as RS232, RS485, RS422, MBUS, CAN, etc.) Socket connection for server communication, and the serial port server itself is used as a protocol conversion device. In the process of communicating with the server, the transparent transmission technology is used for data processing, that is, the serial port server is responsible for suggesting the communication channel of the server, the server polls and controls the device data by actively sending data, and the serial port server sends data to the TCP / IP end It is directly forwarded to the serial port server without processing, and the data received by the data bus terminal is also forwarded without task pr...
